The terms slow and fast fading refer to the rate at which the magnitude and phase change imposed by the channel on the signal changes. The coherence time is a measure of the minimum time required for the magnitude change or phase change of the channel to become uncorrelated from its previous value. • Slow fading arises when the coherence time of the channel is large relative to … WebCite this chapter (2005).
